Specification of Letters Patent. v Patented Aug, 18, 1914},-

Application filed November 26. 1912. Serial No. 733,601.

act description.

he object of the invention is to provide certain new and useful improvements in aeroplanes whereby upsetting is prevented in high winds, sudden gusts, or on the aeroplane passing into air pockets, the arrangement being such that the aeroplane autoinaticall y rights itself if overturned, or taking a header for any reason whatever.

To accomplish the desired result use is made of supporting planes, a keel and tail Wings extending outwardly from the upper edge of the keel, the wings being provided adjacent the keel with openings for the passage of air.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate correspondin parts in all the views.

Figure 1 is a ongitudinal sectional elevation of a monoplane provided with the improvements, the section being on the line 1-1 of Fig. 2; Fig. 2 is a plan view of the same; Fig. 3 is a cross section of the same on the line 3-3 of Fig. 1; Fig. 4 is a cross section of the keel and tail wings, the section being on the line H of Fig. 1; Fig. 5 is a similar view of the head of the aeroplane, the section being on the line ,55 of Fig. 1; Fig. 6 is a perspective view of the body of the aeroplane; and Fig. 7 is a diagrammatic View of the aeroplane iri downward flight.

The supporting planes A and A are-arranged at a dihedral angle, and from the" forward inner portions of the said support ing planes extends a head B forming a continuation of the supporting planes A and A. Tail wings C and C form rearward continuations of the supporting planes A, A

and from the forward portions of the supporting planes A, A and the rear portion of the head B depends a nacelle or well-shaped body D containing an aviators seat E and a motor F for driving the propeller G, which in this case is arranged forward of the head B. A keel H extends from the back of the body D to the rear ends of the tail wings C, C, and the latter are provided .adjacent the keel H with openings C for the passage of air to maintain the aeroplane in equilibrium and to cause the aeroplane to automatically right itself in case it is overturned or takes a header for any reason whatever. The forward portions of the openings C extend into the rear portions of the supporting pla'nes A, A, as plainly indicated in Figs. 1 and A forward keel H extends forward of the body D to the point of the head B, which latter has its forward portions arched in a transverse direction, as lainly indicated in Fig. 5, to assist-in holding the aeroplane in equilibrium during flight.

On the rear end of the keel H is arranged a direction rudder I connected in the usual manner with suitable controlling mechanism I arranged in the body D and under the control of the aviator seated on the seat E. On the rear end of the aeroplane is also mounted an elevation rudder J connected with a controlling device J arranged in the body D and likewise under the control of the aviator. From the body D of the keel or fin H depends a suitable mounting or chassis for supporting the aeroplane on the ground or in the hangar.

The head 13 is preferably triangular-in shape and its base is somewhat less in width than the front edges of the planes A, A.

Having thus described my' invention, T

claim as new and desire to secure by Letters Patent:

1. An aeroplane having supporting planes,

a keel, and tail wings, extending outwardly in opposite directions from the upper edge of the keel, the said tail wings having their outer sides'parallel throughout their length and having openings adjacent the keel, the said openings extending from near the rear ends of the tail wings and terminating in a point in the rear portionsof the supporting planes.

2. An aeroplane having supporting planes extending upwardly and outwardly in oppo- I site directions, and having their outer ends or tips slanting inwardly and forwardly, a head forming a forward'continuation of the said supporting planes, the outer edges of the head also slanting inwardly and forwardly, the base of the head being less in width than the front edges of the planes, 9.

heel, and tail wings extending rearwardly from the supporting planes, the tail wings extending from the sides of the keel andhaw ing their outer edges parallel throughoutback of said body to the rear ends of thesaid tail wings, and a forward keel extendin forwardly from said body to the apex '0 said head, the rear portions of the supporting planes and the said tail Wings being provided with openings adjacent the keel.

a. An aeroplane having supporting planesarranged at a dihedral angle, a triangularshaped head forming a forward continuation of the said supporting planes, tail wings forming a rearward continuation of the stud supporting planes, and having their outer edges parallel throughout their length, a well-shaped body depending from the forward portion of the supporting planes, and a heel extending from the said body to the rear ends of the said tail wings, the rear por- 'tions of the supporting planes and the said tail wings being provided with openings adjacent the? keel, the said openings extending from near the rear ends of the said wings and terminating in a point in the rear portions of the planes.

5. An aeroplane having supporting planes arranged at a'fdihedral angle, a trlangularshaped head forming a forward continuation of the said supporting planes and having its forward portions arched on both sides, tailavings forming a rearward continuation of the said supporting planes, a well-shaped belly dcpei'iding from the forward portion of the su 'iporting planes, and a heel extending from the said body to the rear ends of the said tail wings, the latter being provided with openings adjacent the keel.

6. A n aeroplane having supporting planes arranged a dihedral,anglc, a triangular shaped head forining'ir forward continuation of the said supporting planes, tail wings fi irining a rearward contiiuiation'of the said u planes, a well-shaped body depending from the forward portion of the l l l l l supporting planes, a keel extending from the back of said body to the rear ends of the said tail wings, the latter being provided with o nings adjacent the heel, and a for- Wflld. eel extending forwardly from the said body to the apex of the said head, the said head having its forward portionseroh ed in a transverse direction.

7. In an aeroplane, transversely arranged,

the body of the aeroplane at right angles thereto, the said planeseXtending upwardly and outwardly in opposite direction, the front and rear edges of the projecting portions of said supporting planes being straight and parallel with each other and the outer edges or tips of said planes slanting inwardly and forwardly from the rear to the front of the said planes.

"9. In an aeroplane, transversely arranged supporting planes at the forward portion. of

the aeroplane and extending upwardly and outwardly in opposite directions, tail wings extending rearwardly from the rear inner portions of the planes and forming a con tin-nation thereof, the tail wings having their outer side edges parallel throughout their length, a head projecting from the forward inner portions of the supporting planes and forming a continuation thereof, the laterally pro ecting portions of "the supporting planes having their front and rear edges straight and, parallel with each other, and the outer edges or tips slanting inwardly in a forward direction.

ln testii'nony whereof I have signed my name to this specification in the presence of the subscribing witnesses. J OllN M. DAVIS, i tntss s: 1
